    I was having an argument with class about maximum displacement or maximum draught should be the limiting factor for loading cases . I was following maximum draught(scantling draught) as a limit for loading cases, so , even if i have higher displacement it doesnt matter if my mean draught is suppose equal to 10 m ( scantling draught).

    But the class was saying it will be the maximum displacement at scantling draught as limiting factor for loading cases. so the draught might be less even if i get maximum displacement in the result.

    what you think is correct and why ?

    It's not clear which class society you were having this argument with, nor are the particulars of this argument clearly defined.

    In general, it's not a good idea to argue with class unless they have made some egregious error, like saying 2 + 2 = 5. After all, the society wrote the rules, so they get the final say on interpreting them. The society is not obligated to accept your interpretation, nor are they obligated to class your vessel.

    The idea of a separate scantling draft has also evolved over the years. Most of the class societies with which I am familiar tend to use the summer load line as the scantling draft for applying the class rules. The summer load line is the deepest draft at which a vessel is normally permitted to operate, thus the displacement at the summer load line would be the maximum for which you could develop vessel loading conditions.
